Abstract
The content of heavy metals (Cd, Pb, Zn, Cu, Cr, Ni, Mn and Fe), the grain size distribution and the mineralogical composition was estimated in the bottom sediments of the Vistula and its tributaries: the Rudawa and Wilga rivers. The concentration of metals was variable, depending on the grain size and mineralogical composition, and primarily on the sampling locality. A few samples were subjected to selective chemical extraction to establish the chemical associations of some heavy metals. According to the type of chemical forms, these metals can be divided into two groups: ones showing relatively high mobility (Cd, Zn, Mn) and metals more strongly bonded to sediment particles (Cr, Cu, Pb, Fe, Ni).This publication has 6 references indexed in Scilit:
